5912. Thou, and thy sons, and thy sons' sons. That this signifies spiritual good and all things that are from it and that are from these, is evident from the representation of Israel, who here is "thou," as being spiritual good (of which above, n. 5906); from the signification of "his sons," as being the things that are from this good, which are truths in the natural, and are represented by his sons; and from the signification of "sons' sons," as being the things that are from these, namely, the truths again born and derived. For when good is in the first place, and has dominion, it continually produces truths. It multiplies them around itself and also around each truth, and makes each truth like a little star, in the center of which there is a bright light. Nor does good only multiply truths around itself, but it also produces truths from truths by derivations in succession, which are the "sons' sons," or grandsons; and so on. Joseph invites his brethren to him no otherwise than through his father, saying that he should come with his sons and with his sons' sons. The reason is, that there is no conjunction of the internal celestial with truths in the natural except through the intermediate.
